> Project: HBase
> Issue Type: Bug
> Components: regionserver, rpc
> Affects Versions: 3.0.0-alpha-1, 1.7.0, 2.4.0
> Reporter: David Manning

> HBASE-25212 adds an optional improvement to Close Region, for interrupting
> active RPC handlers holding the region close lock. If, after the timeout is
> reached, the close lock can still not be acquired, the regionserver may
> abort. It would be helpful to add logging for which threads or components are
> holding the region close lock at this time.
> Depending on the size of regionLockHolders, or use of any stack traces, log
> output may need to be truncated. The interrupt code is in
> HRegion#interruptRegionOperations.
